EUROPEAN conformity standards have been rolled out across the drywall and plasterboard production sectors.
All boards, metal components, jointing compounds and plasters should now carry the CE European conformity mark.
The mark shows that the product has been manufactured to comply with the relevant European standards and must appear either on the packaging or the product itself.
Paul Howard, chairman of the technical committee at industry body the Gypsum Products Development Association, claimed the move would benefit installers.
He said: 'The CE marking system will result in clearer and more detailed information being provided on packaging and this will be beneficial to all drywall users.'
The introduction of the marks means manufacturers must display its name, address and year of manufacture.
The information must also include the type and thickness of board and the relevant European standard number.
Mr Howard said: 'The CE mark is not intended to indicate country of origin, nor is it a standard in itself.
'It is conformation that the product has been manufactured in compliance with the relevant standard.'
